Because (I like to think) I’m human, I make models of the world around me. Because I’m a computer scientist/a bit weird, I write them down or draw pictures of them. Since I got interested in why some intelligent people have different political views to me, a couple of years ago, I’ve been trying to model the values which underlie people’s belief systems, which I believe determine their political views.

My working model for the values of Left-Right politics (I’m a fluffy compromise near the middle of this scale but I have other scales, upon which I weigh myself a dangerous radical) has been that The Left believe in Equality and The Right in Selfishness. As a radical liberal, I obviously think both extremes are the preserve of drivelling idiots – compromise is all. The flies in my ointment have been the selfishness of the Far Left and the suicidal economic tendencies of working class nationalists in wanting to #Brexit. My model clearly had flaws.

This morning I was amusing myself with a #UKIP fan who countered being told by a woman that it was best to have O type blood (presumably because it is the universal donor) by saying it was best to be AB, so he could receive any blood (a universal recipient.) On the surface this seems to confirm the selfishness theory but I made an intuitive leap that he thought he was too special to lose, which was far from the conclusion I’d arrived at, during our discussion.

My new, modified theory is that the Left think ‘no-one should get special treatment’ and the Right think ‘My DNA is special. I deserve more’. This belief that “I am/am not special” has almost no correlation with the evidence, or even with class. I have no evidence of whether the characteristic is inherited or learned but Michael Gove and members of the BNP clearly decided that they were special and deserve to be treated better than other people. Tony Benn, on the other hand, argued himself out of believing that he had a God-given right to a place in the House of Lords. Please let me know why I’m wrong.
